Photographic light-sensitive materials containing couplers that release diffusible dyes and DIR compounds

Abstract

A silver halide color photographic light-sensitive material is described, containing: (1) a non-diffusing coupler forming a dye on reacting with an oxidation product of a color developing agent, said dye having diffusibiity of the extent that it exhibits controlled smearing; and (2) a DIR compound releasing a diffusing development inhibitor or its precursor through a coupling reaction. This light-sensitive material is improved in both granularity and sharpness, and has high sensitivity.

What is claimed is: 
     
       1. A silver halide photographic light-sensitive material comprising a support having thereon two silver halide emulsion layers which have different speeds but have sensitivities in the same spectral region, wherein the lower speed light-sensitive emulsion layer comprises a non-diffusible coupler capable of forming a non-diffusible dye by reaction with an oxidation product of a color developing agent and a non-diffusible compound capable of releasing a development inhibitor by reaction with an oxidation product of a color developing agent, and the silver halide emulsion layer having the higher speed contains a non-diffusible coupler capable of producing a diffusible dye by reaction with an oxidation product of a color developing agent, wherein the two silver halide emulsion layers sensitive to the same spectral region are adjacently positioned, and wherein the silver halide emulsion layer having the higher speed further contains a non-diffusible coupler capable of forming a non-diffusible dye by reaction with an oxidation product of a color developing agent. 
     
     
       2. A silver halide photographic light-sensitive material comprising a support having thereon two silver halide emulsion layers which have different speeds but have sensitivities in the same spectral region, wherein the lower speed light-sensitive emulsion layer comprises a non-diffusible compound capable of releasing a development inhibitor by reaction with an oxidation product of a color developing agent, and the silver halide emulsion layer having the higher speed contains a non-diffusible coupler capable of producing a diffusible dye by reaction with an oxidation product of a color developing agent, wherein the two silver halide emulsion layers sensitive to the same spectral region are adjacently positioned and wherein a non-diffusible coupler capable of forming a non-diffusible dye by reaction with an oxidation product of a color developing agent is present in the same layer as or a different layer than the non-diffusible coupler capable of producing a diffusible dye.
